GangEast.safeGunsTransfer(address,uint256) (#1157-1164) ignores return value by guns.transfer(_to,_amount) (#1162)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

HyperCity.updatePool(uint256) (#1393-1409) uses a dangerous strict equality:
- lpSupply == 0 (#1399)
Don't use strict equality to determine if an account has enough Ether or tokens.

HyperCity.enterMechs(uint256) (#1498-1519) performs a multiplication on the result of a division:
-amountAfterRatio = _amount.div(5) (#1502)
-sanitized = amountAfterRatio.mul(5) (#1503)
Consider ordering multiplication before division.
